Unexpected caret move in rich:editor with IE8 + MS IME
------------------------------------------------------

                 Key: RF-11457
                 URL: https://issues.jboss.org/browse/RF-11457
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
         Environment: Windows7/XP
IE8
MS IME(Japanese)
            Reporter: Toshiya Kobayashi


You can reproduce it with http://livedemo.exadel.com/richfaces-demo/richfaces/editor.jsf
I just reproduced with Japanese IME, not sure how other languages work.

- Toggle MS IME on
- Enter "ほんぶん"
- Press SPACE key to change it to "本文"
-- Then the caret moves to the line head. Weird.
- Enter "です"
- "本文" disappears and only "です" remains.

The issue is reproducible only when you write something for the first time to the empty text area. After that, the issue wouldn't happen.
I'm not sure the details of how TinyMCE handles IME keyDown events but the root cause seems to me that TinyMCE doesn't generate <p> tag in the empty text area for IE8 while it does for FireFox and Chrome.

A workaround is populating "<p/>" as the initial value for the rich:editor.

Example)
xhtml:
{code}
<rich:editor id="editor" width="400" height="300" viewMode="visual" value="#{editorBean.value}" ></rich:editor>
{code}

EditorBean:
{code}
private String value = "<p/>";
{code}

This is reproducible with pure TinyMCE 3.2 and the latest 3.4.6 still have a similar issue (The Behaviour is a bit different but <p> is not generated for IE8 yet).
